1. Paste your list, one item per line.
2. Choose an operation from the dropdown.
3. The result updates live. Copy or Download it.

How do I sort a list of lines alphabetically online?

Paste the list and choose Sort A→Z — it sorts instantly in your browser with no upload. Use Sort naturally when the lines contain numbers, so file2 comes before file10 instead of after it.

How do I remove duplicate lines?

Choose Remove duplicates. It keeps the first occurrence of each line and drops the rest; turn off Case-sensitive to treat Apple and apple as the same.

Is my list uploaded?

No — every operation runs locally and nothing is stored. It works with your Wi-Fi off.

What is a natural sort?

A sort that reads embedded numbers as numbers, so item2 sorts before item10. A plain alphabetical sort compares character by character and puts item10 first, which is almost never what you want for filenames or ids.

One operation at a time. Shuffle is seeded so the same list shuffles the same way within a session, which keeps the preview stable.

Duplicate finder counts how many times each line repeats; the word counter measures the text as a whole.
